WATER- MOTOR.

SPIHJCIFICATION forming part of Letters Patent No. 267,672, datedNovember 21, 1882.

Application filed March l0, 1882-. (No model.) i

[o all whom it may concern:

Be it known that I, JOHN G'OATES, a citizen of the United States,residing at Erie, in the county ot' Eric and State of Pennsylvanimlhaveinvented new and useful Improvements in Water-Motors; andl do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to 'the accompanying drawings and theletters or figures of' reference markedthereon.

My invention relates to the construction of water-motors, andparticularly to that class of water-motors known as piston-r'notors.7

The particular object ot' my invention is to. construct a water-motorwhich is peculiarly adapted to operate the bellows of organs. My device,however, is not restricted in its use to the purpose named, butmay beused as a motor for general purposes.

The especial nature ot my improvements and the scope ot' my inventionwill fully appearinthei'ollowinggeneraldescription thereof and thesubjoined claims.

My device is illustrated in the accompanying drawings, as follows: Y

Figure l is a longitudinal vertical section, with some parts inelevationthe line of section in this ligure being theline z z in Figs. 2and 3. Fig. 2 is a transverse vert-ical section on the line a; a: inFig. l, the parts beyond being in elevation. Fig. is a plan view ot'thed under side ot' the cover of the bed A. Fig. 4 is a detail ot'construction. Fig. 2 also shows the connnection ot' the inlet-valves ofthe snpply-pipe with the organ.

The various parts are indicated by letters of reference, as follows:

A is the base of the machine, and contains the valves and valve-gearswithin its chambers A. B is thecylinder; B',the piston-chamber; B2., thepiston 5 B3, the 4piston-rod. U is the valve-`chamber5 U,thevalve; l 2 34, the passages in the valve; cl d', the passages from the valve-chamberto the passages. leading to the piston-chamber; D, the supplyp`assage; cc, the exhaust-passages; I? \l, the passage to the upper end of thecylinder; P2, the passage to the loner end ot' the cylinder. p p are theports. g' is a tappe'L-arm ou the pistonrod. g g are adjustabletappet-collars on the valve-rod. G2 is the valve-rod or tappet-rod.

G is the valve-crank G, the valve which regulates the movement of thepiston in the auxiliary cylinder from which theirain valve is moved. Eis the saidauxiliary cylinder; e, the piston-stem ofsaid auxiliarycylinder; C2, the crank-arm of the main valve. D' D2 are inlet-valves inthe supply-pipe. gan; M, the organ-bellows. L is the winch by which theorganist opens the supply-valve D'. K is a cord connecting said valvewith said winch. I is a weighted arm regulating said valve D. J istheWeight on said arm. I and J are similar devices onthe valve D2. K `is acord connecting the arm l with the b ellows M. F isthe supply-pipe forthe cylinder E. H is the valve-chamber of this cylinder, H H, the waterways or passages, and h the exhaust. i

The construction is as follows: The main cylinder, B, sits on the base Ain a vertical position. which conveys the water 'to and from the upperport, Q. The lower port, p, is in the top of the base. 0n the under sideof the top of the base the castingfi's extended down so as to bring thevalve into proper position, and thus are formed the chambers P'13R-which are in fact parts of thc passages to the ports 1o and p. Theina-in valve U is an oscillating plugvalve. lt is mounted at one end onits stem as a journal and at the other end on a pivotpointedadjustingscrew, N, which holds it so as not to bind or wedge in itschamber. It is provided with Ds or pas'sagcs l 2 3 4, ot'which l is thesupply D, 2 and 3 are exhaust 4. is the back chamber, and is connectedwith the supply D by a veilt or passage, V, which allows the water tolill the chamber 4 and keep the valve balanced. C is the main valvechamber or chest, and has openings c c for the exhaust, and d d forconnecting with the passages P, P', and P2. into the supply passage orchamber D. llhe valve is moved by an arm or lever, C2. The waterexhausted" from the valve-chamber enters the chamber Al in the base A,and finally passes ofi through a pipe, a.. By this arrangement theexhaust is very i'ree and no backpressure will occur. Y

The mechanism for moving the main valve is as follows: An auxiliarymotor, E, is at- It is provided with a passage, P,

7s, andv O is the or- It also has an opening -tached to the cover of thebase A, and lies at as this engine is operated the main valve isoscillated. The time of movement of the auxiliary motor is regulated bythe position of the collars g g on the tappet-rod, and as they can beadjusted as desired the length of stroke of the main piston can beregulated. rlhe object of the auxiliary motor is to secure a fullmovement of the valve by a tappet device and prevent the valve C fromstopping while its faces are passing the ports of the valve-chainber,which it would do if the tappet-rod were connected directly or by leverswith the arm C2, for the reason that the water has no expansive power,and as soon as the pressure is stopped, (as it is the instant the facesof the valve get opposite the ports,) the source of power-wiz., the headot' water-v-is cut oft' from action upon the piston and the motor stops.It' the motor were operating machinery which would run past the point byvmomentum it would be able to pass its faces over the ports; but in anorgan-blower this could not well occur, and the advantage of thisconstruction is that the main pistonrod B3 changes its movement from onedirection to the other without any perceptible jar or jerk.

rlhe mechanism for regulating the supply of water to the motor is asfollows: D' and D2 are throttles in` the supply-pipe, one of which isconnected by a cord with the winch L, or some other suitable device onthe organ, which is accessible to the organist, the other throttle isconnected to the organ-bellows. These throttles are weigh ted similar toa safety-valve on av boiler, and unless held open by the cords will bekeptshutbytheweight. Thethrottleconnected with the bellows is soconnected therewith that when the bellows are collapsed the throttlewill be open, and when the bellows are iniiated the throttle will beclosed. The other throttle is opened or closed at will by the organist.The resultot` this construction is that when the organist opens thethrottle D' the motor will be set in motion, and it' the bellows getpumped full the other throttle, D2, will be closed and stop the motor,thus avoiding all danger of bursting the bellows in case the organistfails to stop the motor when he stops playing upon the organ, or whenthe consumption ot' air is less than the supply. When my motor is usedfor running a gas-machine the second throttle can be connected with thegasolneter and serve as a governor, the same as in the present instance.

In Fig. 4 a detail of construction is shown.

It consists ot' a friction-bearing upon the tappet-rod to keep itfromfalling of its own weight. The bearing is pressed against the rod by aspring, the tension of which is regulated by a screw.

The object in placing the valve at one end ot' the cylinder ot' the mainmotor is to get as speedy an exhaust as possible by utilizing the weightof the water. This position of the valve would be of no specialadvantage it the cylinder was horizontal. Another advantage of this vary motor for opera-ting said valve, also ar.

ranged within said chamber, and, finally, a valve-gear for operating thevalve of said sec ondary motor from the movements of the main motor.

`2. In a water-motor, the combination, substantially as shown, ofthefollowing elements: the hollow base A, with discharge a, the cylinder B,with ports connecting with said hollow base, a valve for supplying waterto and exhausting it from said cylinder, placed within said base, asecondary motor arranged within said base, and connected with said valveby the rod e, and having a valve, G, with arm G', and, finally, thetappet-rod G2 and tappetarm g'.

3. In a water-motor, the valve C', with D- chambers l 2 3 4, and vent orpassage V, substantially as and for the purposes set forth.

4. rlhe combination, with the supply-pipe ot' a watermotor, ot' twothrottles or shut-off valves, D' D2, having cords for the purpose setforth, of mechanism which, when valve D' is opened, opens and closesthrottle D2, for the purpose set forth.

5. The combination, with the supply-pipe ot' a water-motor, ot' twothrottles or shut-ofil valves, D' D2, the first operated by hand and thesecond by the action ot' the mechanism to los IIO

which it is attached, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of March, 1882.
